PSM and ABS Failure

10 posts in this topic

Well, I get this error (PSM Failure, ABS Workshop... something like that), and ABS does not work... stability program does not work also.

They told me at the dealership, that the ABS module is fried.

Hmmm, ok, but:

1. Is the ABS module controling the PSM also ?

2. Can I use one from a damaged Cayenne, to replace this one ? they are charging close to 1500 eur for a new one...

3. Is it interchangable with what Cayenne Models ?

Please advise :)

Mine is a 2004 Cayenne Turbo.

I've already change parts in amount of allmost 3000 euros in 2 days... jeez, c'mon :huh:

1. Yes, they work together

2. Yes, perhaps. The ABS control units have changed several times (5 that I count) and their is a TSB that shows which control unit can be used in which VIN cars. Sp you would need to find a matching donor.

3. See 2.

I show a US MSRP of about $700 for the ABS controller so the rest must be labor. You might try to negotiate the labor given your recent costs -- or get an outside quote from an independent shop.

Ok, thank you very much. :)

One more thing please... Is there a way to check my VIN, against other models, to see what other vehicles are compatible with my car, in terms of this ABS module ? A site or whatever...

I suspect the dealer to overcharge my bills :unsure:

edit: what is TSB ?... Sorry i am not familliar with the terms...

See our Glossary link at teh top right of the forum.

TSB = Technical Service Bulletin. Porsche issues TSB's for part number changes, installation of options and accessories, approved oils, tires, wheels, etc. Recalls are NOT covered in TSB's.

Ok, i will check this out.

Anyway, is it possible, that only one sensor (on a wheel) could be defective ? and so I get this PSM + ABS Failure message ? And maybe the control unit is fine ?

If it was a speed sensor you would get a code for whatever sensor was affected. Any ideas what faults codes were recovered?

Well... no, the report remained at the dealer, ****.

I am under the impression they are screwing with me, this explains maybe all my questions -_-

I felt the ABS kicking in, on three wheels, except for one - REAR LEFT ! Of course, the message on the dash is "PSM, ABS Failure...bla bla"

Your input is very helpfull, thank you for this :)
